JL2 4.5" RT4 Long Arm Lift - No Shocks

TeraFlex Alpine RT (Rogue Trail) Suspension Systems build on our already capable Alpine CT (Cross-Trail) Suspension Systems. These systems include all our top-of-the-line components. The 4.5" Alpine RT4 Long Arm Suspension System excels on the highway, off-road, through the desert, or rock crawling! TeraFlex suspensions are built on decades of research and development resulting in the ultimate suspension with a lifetime warranty. Bolt-on Alpine IR Long Control Arms & Brackets, HD Forged Adjustable Front Track Bar, and Front and Rear Track Bar Brackets allow full suspension adjustability, while the SpeedBumps smooth out unexpected trail bumps. Adjustable Alpine IR Long Control Arms balance front caster and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 3-6" lifts. On higher lifts, Alpine Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during extreme droop as well as shock load transferred through the control arms. HD Forged Adjustable Front Track Bar and Front and Rear Track Bar Brackets improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling. Alpine IR Control Arms feature our all-new IR (Independent Rotation) Bushings. These innovative bushings remove bushing bind during full suspension travel for less overall bushing load during articulation resulting in unrestricted droop as well as a noticeable ride improvement whether on the highway or the trail. This results in improved suspension geometry and relaxed control arm angles for a superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH). Alpine RT Suspension Systems are for the Jeeper who wants it all!
